Activating Compound

Activating Compound Comment Organism Structure
Calmodulin at a separate concentration of Ca2+ and calmodulin of 0.2 mM and 150 nM, the rice bran GAD is significantly enhanced 3fold. Addition of exogenous EGTA or TFP efficiently inhibited the stimulatory effect of Ca2+/CaM complex Oryza sativa
